DST4602Evolution is the top-level device among SICES controllers.
It is an highly configurable genset controller for advanced and complex parallel applications, where a huge number of settings are required (functions and parameters) for the genset management, and its auxiliary circuits.

DST4602Evolution allows to connect up to 24 gensets on the same bus, working in island mode and in parallel with the mains.

Thanks to the controller’s high configurable level and built-in PLC functions (with PID blocks), DST4602Evolution can be used for CHP power plants equipped with Gas, Diesel, Biofuel and Dual fuel Engine.
The controller also features fully integrated Air-Fuel Ratio (AFR) control, furthering its ability for such applications.

Further details
DST4602Evolution is fully equipped with internal Load Sharing, Synchronizer and W and VAR regulation. This controller includes a CAN J1939 interface, supporting a wide range of engines (Volvo Penta, Scania, Perkins, MTU, Deutz, Cummins, John Deere, Caterpillar and others).
It can be also used with traditional engines, where measurements and control are performed by the embedded analogue interfaces.

DST4602Evolution can be used together with all Sices genset controllers (GC600, GC400). In case of multiple gensets in parallel with the mains where the reverse synchronization is required, and it can be also interfaced with the Sices mains controllers (MC200, MC400), to avoid in this way any further blackouts on the loads.

The controller’s configurable parameters make standard and customized tasks easy to manage. All the parameters can be set directly by the controller’s keyboard or, alternatively using the free software tool (BoardPRG3), available from SICES’ website. It is also available a free PLC software editor, (SicesPlcEditor) to set the PLC logics.

The enhanced and large 7” graphic colour display with TFT technology, is a user-friendly interface, conceived for a quick and easy visualization of measures and alarms coming from the genset. This controller stores events and periodical data in the internal memory, this information can be read from the front panel display.

DST4602Evolution provides several communications interfaces for local or remote control. In case of complex applications, like Oil&Gas stations, the inbuilt protections can be expanded by using the external protection relay D-PRO.
